The CD-P00-U Series Duct CO2 Transmitter uses a highly accurate and reliable nondispersive infrared (NDIR) sensor in a low profile enclosure with a gasketed, hinged cover for duct applications to monitor CO2 levels. The sensor uses dual channel optics and long-term adjustment signal processing technology to deliver industry leading long-term accuracy and reliability. These features ensure optimum measurement stability for continual monitoring of either supply or return-air measurement
The Johnson Controls CD-P1000-00-00U CO2 transmitter, duct mount
The Johnson Controls® CD-Px0xx-00-00 Series duct mount transmitters are designed for the measurement of CO2 and temperature in HVAC applications where demand control ventilation (DCV), fresh air and indoor Air Quality (IAQ), and rooftop air handling economizer control systems are often required.
The CD-P Series sensors incorporate a dual wavelength non-dispersive infrared (NDIR) CO2 sensor, which compensates for aging effects, is highly insensitive to pollution, and offers outstanding long-term stability.
The CD-P1000-00-00U transmitter is available with CO2 output only, 0 to 10 V or 4 to 20 mA while the CD-P2000 Series offers CO2 and temperature measurement with active or passive outputs. A multiple point CO2 factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range.
Features and Benefits
- Adjustable duct probe depth—Permits optimal placement of sensing tip in a duct.
- Support for DCV—Offers potential for 10 to 70% energy savings.
- Single-beam dual-wavelength NDIR CO2 sensor—Is highly insensitive to pollution with outstanding long-term stability.
- Models include CO2 and CO2 + temperature outputs—Reduces installation time and cost.
- 0 to 10 V or passive temperature output—Is suitable for a wider range of applications.
- Factory calibration certificate—Includes test report according to DIN EN10204 – 2.2.
Product Overview
This transmitter uses NDIR CO2 sensing technology and operates in accordance with the single-beam dual-wavelength method. The sensor offers excellent stability over both time and temperature.
The transmitter is factory set to measure CO2 levels up to 2,000 (ppm). It requires a 24 VAC or 15 to 30 VDC power source and generates an output signal proportional to the CO2 level detected.
The duct-mounted CO2 transmitter Series offers:
- CO2 transmitter with 0 to 10 V or 4 to 20 mA output, field-selectable.
- CO2 transmitter with 0 to 10 V or 4 to 20 mA output field-selectable and temperature output 0 to 10V.
- CO2 transmitter with 0 to 10 V or 4 to 20 mA output and passive temperature output Pt1000 or NTC10K
